“Planting trees, I myself thought for a long time, was a feel-good thing, a nice but feeble response to our litany of modern-day environmental problems. In the last few years, though, as I have read many dozens of articles and books and interviewed scientists here and abroad, my thinking on the issue has changed. Planting trees may be the single most important ecotechnology that we have to put the broken pieces of our planet back together.”

“Plant trees. They give us two of the most crucial elements for our survival: oxygen and books.”

“Most days, for the last dozen or so years, I attributed to Charlie, or at least to our breakup, most things that have gone wrong for me. Like: I wouldn't have packed in college; I wouldn't have gone to work in Record and Tape; I wouldn't have had an unsatisfactory personal life. This is the woman who broke my heart, who ruined my life, this woman is single-handedly responsible for my poverty and directionlessness and failure, the woman I dreamed about regularly for a good five years.”

“It's Earth day I wonder if we can plant more trees than people for a change?”

“We have a responsibility toward the other life-forms of our planet whose continued existence is threatened by the thoughtless behavior of our own human species. . . . Environmental responsibility – for if there is no God, then, obviously, it is up to us to put things right.”

“People often ask, "What is the single most important environmental population problem facing the world today?" A flip answer would be, "The single most important problem is our misguided focus on identifying the single most important problem!”
